Braves 9, Giants 8 (12 innings)
ATLANTA -- Third baseman Adonis Garcia hit a two-run homer in the bottom of the 12th inning to give the Atlanta Braves a 9-8 win over the San Francisco Giants on Monday.
Second baseman Jace Peterson reached on an error to open the inning and Garcia followed with his third homer of the year to beat Ryan Vogelsong (7-7).
Catcher Buster Posey had given the Giants an 8-7 lead in the top of the 12th inning with an RBI single. With one out in the 12th, Giants rookie Kelby Tomlinson made his major-league debut with a single against Ross Detwiler, who followed that by hitting center fielder Gregor Blanco with a pitch.
The Braves brought in hard-throwing Arodys Vizcaino, who gave up a long fly to center that allowed Tomlinson to advance to third base. Posey then laced a single into right-center field to drive in the go-ahead run.
Vizcaino (2-0) was the winning pitcher.
The Braves sent the game into extra innings when catcher A.J. Pierzynski hit a two-run homer, his seventh, against San Francisco closer Santiago Casilla with two outs in the ninth inning. That tied the game at 7-7.
The Giants hit four home runs, two of them by shortstop Brandon Crawford, and one each by first baseman Brandon Belt and Posey and had a 6-0 lead after four innings.
San Francisco starter Matt Cain allowed 10 hits and never retired the side in order, but was aided by two double plays and went unscathed until the sixth. That's when the Braves rallied for four runs, with Peterson's three-run homer being the big blow.
Garcia followed the homer with a double down the line, which chased Cain. Reliever George Kontos retired the next two batters, but allowed an RBI single to right fielder Nick Markakis that cut the lead to 6-4.
Atlanta drew to within one in the seventh when first baseman Chris Johnson hit a long solo homer to center field, his second, against reliever Hunter Strickland.
The Giants added a run in the ninth against reliever Andrew McKirahan. Left fielder Nori Aoki singled with two outs to drive in second baseman Ehire Adrianza to make it 7-5.
Atlanta starter Mike Foltynewicz allowed six runs on nine hits and one walk.
